Description

A kind of phosphoric acid tail gas processing system
Technical field
This utility model belongs to field of chemical equipment, in particular it relates to a kind of phosphoric acid tail gas processing system.
Background technology
During producing phosphoric acid, need to wash the tail gas produced on its production line, one is for qualified discharge, Two is to recycle utility in tail gas.Slurry concentration process monoammonium phosphate device is high-concentration phosphate compound fertilizers production line, its drying tower tail Although the process of gas is not main production link, but the quality of its flow setting and equipment operation is to the yield of device, fortune Rate of rotation, material recovery rate, energy consumption level and environmental conservation all have a great impact.Owing to drying tower outlet dust content is higher, It is MAP finished product, and because drying tower tail gas water capacity out is the highest.If tail gas is directly discharged to air, phosphorus ammonium tail In gas, band liquid, band dust, cause the pollution of loss of material and environment.
Utility model content
The purpose of this utility model is to provide the phosphoric acid tail gas processing system that a kind of cleaning efficiency is high and cleaning effect is good.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of phosphoric acid tail gas processing system is provided, including pipeline, sets gradually extraction tank, one-level washing dress along described pipeline Put, two grades of wash mills and tail gas funnel, described one-level wash mill includes Venturi tube, the fluorine silicon being sequentially connected with along pipeline Acid circulating slot and channel washer, described Venturi tube is all connected with described hexafluosilicic acid circulating slot with the bottom of channel washer, institute Stating extraction tank air inlet superposed with Venturi tube to be connected, described two grades of wash mills include tail gas washing tower and foam removal tower, Described channel washer gas outlet is connected with described tail gas washing tower air inlet, described tail gas washing tower gas outlet and described foam removal Tower air inlet connects, and described foam removal tower is connected with described tail gas funnel, and is provided with water inlet below described tail gas washing tower, described Foam removal tower is arranged over shower.
Further, between described foam removal tower and tail gas funnel, it is provided with exhaust fan.
Further, in order to ensure the abundance that supplies water, described tail gas washing tower water inlet and shower are all connected with industry water pipe And running water pipe.
Compared with prior art, the beneficial effects of the utility model are:
In this utility model, phosphoric acid tail gas system is under the effect of exhaust fan, the trachea at extraction tank exhaust gas flow direction top, Enter in Venturi tube and channel washer, wash as one-level.Two grades of washings are carried out subsequently into tail gas washing tower, foam removal tower. It is discharged to chimney through exhaust fan after.In Venturi tube, detersive efficiency is high, effectively reduces delivery temperature.Add foam removal tower, it is ensured that The cleaning of exhaust emissions.In order to prevent the silica gel carried secretly in tail gas in impeller and chimney bonding, in foam removal tower use spray Pipe is sprayed water, and makes temperature reduce, and solid phase separates out sedimentation further.
Accompanying drawing explanation

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.
Refering to shown in Fig. 1, a kind of phosphoric acid tail gas processing system, including pipeline 1, set gradually extraction tank along described pipeline 1 2,3, two grades of wash mills 4 of one-level wash mill and tail gas funnel 5, described one-level wash mill 2 includes along pipeline 1 successively Venturi tube 31, hexafluosilicic acid circulating slot 32 and the channel washer 33 connected, described Venturi tube 31 and the bottom of channel washer 33 All being connected with described hexafluosilicic acid circulating slot 32, described extraction tank 2 air inlet superposed with Venturi tube 31 is connected, described two grades Wash mill 4 includes tail gas washing tower 41 and foam removal tower 42, described channel washer 33 gas outlet and described tail gas washing tower 41 Air inlet connects, and described tail gas washing tower 41 gas outlet is connected with described foam removal tower 42 air inlet, described foam removal tower 2 and described tail Gas chimney 5 connects, and is provided with water inlet 411 below described tail gas washing tower 41, and described foam removal tower 42 is arranged over shower 422。
Further, between described foam removal tower 42 and tail gas funnel 5, it is provided with exhaust fan 6.
Further, described tail gas washing tower 41 water inlet 411 and shower 422 are all connected with industry water pipe and tap water Pipe.
Concrete, in this utility model, phosphoric acid tail gas system is under the effect of exhaust fan 6, extraction tank 2 exhaust gas flow direction top The trachea in portion, enters in Venturi tube 31 and channel washer 33, washs as one-level.Subsequently into tail gas washing tower 41, foam removal Tower 42 carries out two grades of washings.It is discharged to tail gas funnel 5 through exhaust fan 6 after, adds foam removal tower 42, it is ensured that exhaust emissions clean Only.In order to prevent the silica gel carried secretly in tail gas in impeller and tail gas funnel 5 bonding, in foam removal tower 42 use shower 421 Water spray, makes temperature reduce, and solid phase separates out sedimentation further.
The above embodiments are only preferred embodiment of the present utility model, it is impossible to limit right of the present utility model with this Scope, therefore, the equivalent variations made according to this utility model claim, still belong to the scope that this utility model is contained.
